Description

[Detailed description of the invention] This invention is a wrap-around (wrap-a, ro
The present invention relates to a helmet that includes components forming a helmet assembly, referred to as an integral type.

Conventional helmets of this type, used by motorcyclists, car drivers, skiers, etc., include a rigid cap with an open bottom to admit the user's head.

In order to secure the helmet to the user's head, the user's head is introduced into the helmet by opening the non-deformable member attached to the cap by a chinstrap with a buckle or a hinge joint, and then A technique is employed in which the chinstraps or members are brought close together and secured with suitable fasteners.

However, the above-mentioned conventional techniques have various disadvantages, and the manufacturing cost thereof may be very high.

In fact, such chinstraps are very narrow and can only cover a small portion of the user's lower chin, making them extremely dangerous.

In addition, the opening member attached to the gap of the helmet cap with a hinge has a complicated structure and the parts are expensive.
It was also time-consuming to manufacture.

A first object of the present invention is to provide a helmet that can eliminate various problems of prior art helmets.

A second object of the present invention is to provide a helmet that can be fixed to the user's chin without using a chin strap as an accessory.

Another object of the invention is to provide a hard hat with an opener that does not require a hinged connection.

Yet another object of the invention is to provide a hard hat having a secure closure mechanism that is simple to manufacture and convenient to use.

These and other objects, which will become apparent from the following description, are comprised of a rigid head cap with sloping visors, the head cap being fully open at its bottom and having a padded 5- partially closed by a resilient split ring member, the split ring member being elastically deformable and attached to the rear of the head cap of the hard hat and a detent on the portion of the hard hat that is secured to the jaw of the head cap of the hard hat. This is realized by a helmet cap characterized in that the free end of the inner part engages forward at the inner split part.

Further features and advantages of the invention will be apparent from the following description of a preferred embodiment with reference to the accompanying drawings:
It will become even clearer.

In FIG. 1, the helmet cap according to the present invention is composed of a head cap 1 made of a rigid material having impact resistance. is provided.

The bottom of the head cap 1 is fully opened, and is fixed to an L-shaped part 3 that runs along the nape of the neck and a part 5 that surrounds the bottom of the opening that is provided substantially in the center and covered by the paralysis 2. and a front lug 4.

In this way, the head cap 1 has two -0- opening side parts 6 extending in an arc from the front central part to near the nape of the neck on the tangential side.

Naturally, the inside of the head cap 1 is padded with a suitable cushioning material.

The helmet cap according to the present invention further includes a split metal ring 7, and the split metal ring 7 has an upper portion 8 disposed along the nape of the neck of the helmet cap 1, and is elastically elastic when the helmet cap is closed. It consists of a bent elastic metal piece with two additional side parts 9 and 10 taking the positions 9a and 10a shown in FIG.

Centering around the elastic split metal ring 7, the padding 11.12 shown in Figure 4 of C1 is applied, extending to the interior 13.14 to restrict the downward opening of the helmet cap and fix it to the user's chin. .

The two additional sides 9.10 are provided with front latches, and when these front latches engage with the front lug 4, the additional sides 9.10 are elastically deformed and moved closer to each other,
Close the helmet.

As shown in FIG. 5, during assembly, the elastic ring is inserted into the head cap 1, and the upper part 8 of the split metal ring 7 comes into contact with the 1-shaped part 3 of the head cap 1. This will allow it to be held more firmly in the shape of the letter. The additional sides 9, 10 are thus arranged on the open side 6.

Of course, another device may be added to fix the split metal ring 7 to the head cap 1 if necessary.

Furthermore, deformable parts 15,16 are provided which facilitate the partial deformation of the additional side parts 9,10.

By bending the split metal ring 7, the additional side portion 9.
10 can be opened and moved apart from each other or close to each other.

111, by operating the device that fixes the end of the additional side part 9.10 to the front lug 4, the additional side part 9.10 is automatically snapped open and the helmet cap is removed. unlock.

In this case, in order to release the helmet after opening the front device, the additional side portions 9 at positions 9a and 10a as shown in FIG.
, 10 are manually opened outward and sufficiently elastically deformed to remove the helmet from the user's head.

It is clear that the helmet according to the invention allows the lower part of the helmet to be opened and passed over the user's head without the need for hinges as required with prior art helmets. be.

From the viewpoint of manufacturing and usefulness, the shape of the split metal ring 7 may be changed within a range that does not impair operability and practicality.

Furthermore, instead of the single split metal ring 7, two separate metal pieces may be attached to the rear of the head cap 1 to elastically deform the parts for fixing the helmet to the user's head. good.

Furthermore, the split metal ring 7 is fixed to the front part of the helmet cap, which is attached to the user's chin, so that it can be opened at the same time, and the free ends of the additional side parts 9, 10 are secured by suitable latching means. It may also be engaged with the head cap 1.

The helmet cap according to the present invention has a manufacturing aspect of 33%.
In the simplest case, it is particularly advantageous that two individually completed parts can be assembled together in one operation.

The helmet cap according to the present invention does not require a fil) device or a rotating device tG, so it is simple in construction and prevents malfunctions and N.
1, who can attack by 1 inch as much as possible,
Since the split metal ring 7 having elasticity in the shape of ML is used for the normal opening operation, a spring device for automatically opening the opening part of the Bermetsu L-cap can be omitted.

Based on the technical idea of this invention, various changes and modifications may be made without departing from the scope of this invention.
It's quite possible.

Furthermore, materials, dimensions, etc. can be selected according to individual needs.
